vide ways in which the sash may slide vertically and adapted to prevent the sash from binding in the frame due to swelling or warping of the wood sash or frame.

Another object of the invention is to pro- 1o vide a sash guide, including aI parting stop and weather strips, adapted to be nailed to the sides and top of a window frame to provide the ways in which the upper and lower sash may ride.

A further object of the invention is to provide a metal sash guide so arranged that the wood sash are shielded by metal from contact with the wood of the window frame -to prevent wood to wood contact between the sash and frame and allowing the sash to slide freely in the frame at all times.

These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is shown in the accompanying drawings in which'- Fig. 1 is an elevation of a window frame showing the sash guides in dotted lines mounted therein.

Fig. -2 is an enlarged section taken on line 2-2 of Fig. 1 and showing both sash in the raised position.

Fig. 3 is a perspective view of the metal sash guide showing the meeting rails of the sash in dotted lines covering the joints between the upper and lowersash guide members.

The sash guide is formed of sheet metal and is formed to provide a way 1 for the upper sash and a way 2 for the lower sash. The metal in each way is formed with a raised rib 3 extending longitudinally thereof and riding in a groove 4 provided in the respective sash and forming a weather strip. At the center the metal is formed to provide a raised parting stop 5 shown in Figs. 2 and 3 which forms a parting stop between the upper and lower sash. The sash guide is provided with an inturned Aedge 6v at the outer edge and an inturned edge 7 at the inner edge extending in parallel relation with the weather strip ribs 3 and partin top 5. In mounting the device in the side o a window frame the sash guide is made'in two pieces which meet at 8 behind the meeting rails of theupper and lower sash. In this way the upper sash guide is held in alignment with the lower sash guide and the sash will readily ride over the joint between the two guide members 4without sticking. The sash guide members are secured to thel window frame by means of nails or screws 9 and the inturned edge 6 which forms the outer edge of the sash guide abuts against the blind stop 1() on the outer face of the window frame.

The inner edge 7 abnts a ainst the inner window stop 11 as shown in ig. 2 and as the parting stop 5 is formed in the center of the sash guide there is no necessity of providing a separate parting stop. For this reason it is unnecessary to groove the window frame 12 and therefore any straight ungrooved piece of vmaterial may be used for the window frame member 12.

For a cheap construction such as in summer cottages or the like the sash vguides ma be nailed directly tothe studding surroun ing the window openings and will thus provi e ways for the sash without the expense of providing a window frame. As the sash guides provides Weather strip protection as well as rotection against the sash sticking in the rame considerable improvement is provided over the ordinary window. In buildings where this type of sash guide is used the weather strip ribs 4 are always at the same distance from the parting stop and in the same position in relation to the sash and therefore the sash may be grooved for the weather strip at the mill where the sash is made.

One of the objections to the ordinary wood- With my device when paint is carried over onto the metal it can readily be wi ed off as it does not adhere well to the meta and thus the free operation of the sash is not impeded. This device may also be used in old buildings by simply removing the parting stop before the sash guides are mounted .in the positlon or, if desired, the metal parting stop 5 may be positioned directlyover the ordinary wooden parting stop. The sash guides may be made of zinc, copper, brass, bronze or other metal, it being preferable that a metal be used which does not tend to rust as it is necessary to maintain a clean surface so that the sash will slide freel at all times. With this device mounted as s own in Fig. 2 it will be noted that the sash do not come in. contact with the window frame at any point and as the sash ide is carried up on both sides and across tgl; top of the window frame as shown in Fi 1 weather. strip protection is provided on tle sides of the window frame. A metal strip may also be provided on the window sill if desired to weather strip the fourth side of the window opening and a weather strip may or may not be used as desired between the meeting rails of the upper and lower sash.

From the foregoing description it becomes evident that the device is very simple and eilicient in operation, may be easily made and installed, is of low manufacturing cost and provides a device which accomplishes the objects described. f

Having thus fully described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is 1. A sash guide comprising a strip of sheet metal formed to provide a parting sto extending centrally thereof longitudina y of the strip, the opposite edges of the strip being inturned in spaced relation with the parting stop and forming a sash groove on each side of the partingstop, a weatherstrip rib formed of the metal in the bottom of each sash groove and extending upwardly into the sash groove in spaced relation with the parting stop and the inturned edges of the sash gulde, the sash guide being adapted to be secured to the opposite sides and across the top of a window frame to provide ways in which the sash may slide.

2. A sash guide comprising a strip of sheet metal formed to provide a parting stop ex- In testimony 'whereof I sign this specification.

tending longitudinally thereof through the .center the outer edges of the strip being turned inwardly in spaced relation with the parting stop and forming sash grooves each side of the parting stop, the strip bein formed to provide a weatherstrip rib on eac side of the parting stop in the bottom of the sash groove extending longitudinally of the sip in parallel relation with the parting s p.
